Specification of Letters Patent.

Patented Allg. 17, 1920.

To all 'whom t ma concern:

Be it known t at we, RICHARD PHELAN and Flnnnlucx Bnmux, citizens o the United States, residing at Oakland, in the county of Alameda, and in the city .and county of San Francisco, respectively, in the State of California, have jointly invented a new and useful Improvement in berths, of which the following is a specification.

Our invention relates to improvements in steamer berths and the like wherein. an upper and lower berth, operate in conpnus-- tion with improved means for pivotally and resiliently suspending said berths between the walls of a ships com artment to pre vent the transmission of he lateral movement and vibration of said ship to said berths.

The primary object of our invention is to provide a new and improved berth for Steamers and the like.

A further object of the invention is to provide an im roved berth suspended pivotally and resi iently to prevent the transmission of the vibration and lateral rolling of the ship tosaid berths.

A still further object of the present in 4vention is to provide improved means for normally and automatically maintaining said berths in a horizontal plane.

It. is. also an object of the present invention to provideV upper and lower berths of a pendulous nature and adapted for movement within a limited space, relatively to the ships compartments within which they are ivotully and resiliently suspended.

e accomplish these and other. objects by means of the improved device disclosed in the drawings forming a pigrt'of the presentyspecification wherein 1i characters of reference are used to desi atc similar arts thrdughout the said spec tion and rawin s; and` in which y 1gnrel`l1 is l vertical, breken sectional view of afportion of e shi, s compartment disclosing the manner o pivotally and resiliently uspending the berths; and

Fig. 2 is a broken end Aelevation of the berths. l l

Referrin to the drawings the numeral 1 is used to -desigllte the opposite walls of a ships compa'rtmet, echwall having a vertically disponi@ Blot- 2 therein said slots being arran l ed opposite each other.

Alined a ove eachslot 2 and mounted upon the walls l is a bracket 3 within which brackets 3 are slidubly mounted for vertical movement only the pins 4 havingr enlarged heads 6 resting upon suitable springs 7.

An upper berth 8 is provided with brackets 9 pivotally engaging the lower ends of the pins 4, said pivotal points being a1'- ranged above and coaxial with the longitudinal center of the seid upper berth R.

A lower berth 1l is provided with brackets 12 on euch end thereof arranged to pivotal] and slidably engage the slots 2 of the wel s 1.

Connecting rods 14 pivotally connect the corners of the uiper and lower berths 8 and 11 res ective y whereby parallel positions may assumed by said berths when moved on tlieir pivotal points.

A pendulum weight 16 is secured to the lower berth 11 by means of which, and the connecting rods 14, lioth berths 8 `and 11 may be normally and automatically retained in a horizontal plane during the rolling of the shi within a comparatively limited space. hat is, the pivotal points of each berth being mounted for vertical as well as pivotal movement, it is evident that the `lower berth, instead of swinging from the pivotal point of the up )er berth, will swing from its own independent pivotal point as represented by the brackets 12 and slots 2. the plane of the upper berth 8 being re tained parallel to the lower berth l1 by means of the connecting rods 14, which novel arrangement and feature will shorten the radius of the arc through which the lower berth 8 swings.

Upon the lower surface of one end of the lower berth 11 we have mounted a sector 17 provided with notches or recesses 18 enga able by a toothed locking-weight 2() slide ly mounted for vertical movement Within a plate 22 secured to the adjacent wall 1 of the compartment.

A cord 23 is secured to the locking weight 20 and asses over a suitable pulley 24 directly a ve said lock-weight 20 and thence over a second pulley 26 and to an arm 27 upon a vertical y disposed .rod 28 rotatably mounted uponthe adjacent wall 1 of the compartment. The rod 28 is provided with operating handles 29 conveniently 1Q- cated adjacent the head of each berth so that by means of said handles 29 rod 28 may bc partially rotated to move the erm 27 and thereby pull the cord Z3 and raise the locking-weight 20 to disengage the same from the teeth 18 of the sector 17 thereby permitting movement of the berths 8 and 11 relatively to the ship.

The locking-weight 20 may be locked in disengaging position by moving the arm 27 ast a center line drawn between the pulley 26 and the center of said rod 28 whereby tension of the cord occasioned by said weight will tend to move the arm 27 against the wall 1 and thereby prevent lowering of the weight 20.

From the foregoing it is obvious that the berths, being -reslliently sus ended will be free of vibration as such vibration of the ship will be absorbed by the springs 7. It is also obvious that the pendulum weight 16 will tend to retain the berths 8 and 11 in a horizontal plane and in parallel position to each other through the medium of the connecting rods 14.

Having thus described our invention what We claim as new and desire to secure by Letters Patent is- 1. A 'non-vibrating berth comprising a berth having brackets at each end thereof whereby said berth may be suspended; and means for pivotally and resiliently engaging the brackets to prevent transmission of vibration and lateral movement of a shiip lwithin which the berth may be suspended,

to said berth, and means shdably engaging the berth for locking said berth against lateral movement an permitting vertical movement relatively to said ship.

2. A non-vibrating berth for ships and thelike comprising opposite compartment walls on said ship; brackets mounted opposite each other on said walls; pins mounted for vertical movement within said brackets; means for resiliently resisting said vertical movement; a berth pivotally connected to the pinswhercby transmission of vibration of said berth may be prevented; a second berth arranged below thc first berth; and suitable connecting rods connected to each corner of both berths whereby said second mentioned berth may be pivotally suspended from said first mentioned berth;

brackets secured to each end of the second mentioned berth, and means secured to the compartment walls for slidably engaging said brackets for vertical movement whereby movcment of the first mentioned berth may be duplicated and transmitted to said second mentioned berth.

3. A non-vibrating berth for ships and the like comprising an upper andl lower berth; connecting rods connecting the berths at their corners', pivotal brackets mounted upon each end of each berth; means for slidably engaging the brackets of the lower berth; and resilient means for pivotally engagin the brackets of the upper berth; whereiy transmission of vibratlon of the ship to both berths may be prevented.

4. The combination with a ship of op osite compartment walls havin vertica ly disposed oppositely arranged s ots therein;

a palr of pins alined with and mounted for vertical movement above the slot; means fo`r resliently supporting the pins; an upper and a lower berth mounted between the pins and slots respectively; connecting rods pivotally connecting the corners of the berths; brackets on the ends of the upper berth pivotally engaging the pins; an brackets on the ends of the lower berth pivotally and slidably engaging the slots in the compartment walls w ereby both berths may be resiliently and` pivotally suspended to prevent the transmissionof lateral movement and vibration of said ship to said berths.

5. The combination with a. ship and compartment therein of a pair of berths arranged one above dependent pivotal points arranged above the longitudinal center of each berth; means for pivot-.illy connecting the corners oi both berths; means for slldably and pivotally engaging the pivotal points of the ower berth; and resilient means pivotally connected to theypivotal points of the upper berth whereby transmission of vibration and rolling of said ship to said berths may be prevented.

In witness whereof we hereunto set our signatures.
